[Nero Germanicus]

Of the nine Republicans who voted no, only two are up for reelection in 2018: Corker of Tennessee and Heller of Nevada.
The no votes: Susan Collins (Maine), Bob Corker (Tenn.), Tom Cotton (Ark.), Lindsey Graham (S.C.), Dean Heller (Nev.), Mike Lee (Utah), Jerry Moran (Kan.), Lisa Murkowski (Alaska) and Rand Paul

[Repeal The 17th]

My notes for Tennessee show that Larry Crim has announced that
he will run against Bob Corker in the primaries.

I do not see a challenger for Nevada’s Dean Heller

[octex]

I recall that POTUS Trump previously stated that he would support a GOP candidate running against Heller in NV.
